IMPROVEMENTIN FARM-GATE.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, JONATHAN DAVID, of East Enterprise, in the county ofSwitzerland, and State of Indians, have invented new and usefulImprovements in Farm-Gates; andI do hereby declare that the followingisa full, clear, and exact description thereof, which will enable thoseskilled in the art to make and use the same, reference being had to theaccompanying drawings, forming part of this specification.

This invention has for its object a cheap and convenient farm-gate, onenot liable to get out of order, and which, by reason of the front stilerising when the bolt is drawn back, avoids all obstruct-ions to its freeswing, such as snow-drifts, frozen clods of earth, or the ultimatesagging downwards of the front stile, resulting from the constant straintendingto that end, so often found in large gates. a

Another important object is to construct the gate so that it may behoisted vertically to a limited height, so that the smaller domesticanimals may pass under without permitting the larger ones to do so.

I Figure 1 is an elevation of the gate, closed. I

Figure 2 is a view of the same, hoisted.

Similar letters of reference indicate corresponding parts. i

A and A are the gate-posts. In A is cut the mortise or socket, s, forthe bolt G. C is the hanging stile,

D'the top rail, and E a double brace. These form a species of crane. Therails, a a a a are hungon wooden pins, 1 2 3 4, which pass through thestile C, said stile being slotted for the admission of the rails. Theserails,

.pass through the double brace E, and are hung at their other ends onthe pins6 8 9, in the double'front stile C. H is a double strip, pinnedto the upper and lower rails, to serve as a guide for thesaid rails, andfor the bolt Gr. F is the lever for operating the bolt; it is forked forabout two-thirds of its length, and passed over the top rail D. The pin2' passes through the forks of the lever and the rail a, which forms afulcrum. Another pin, near the lower end of the lever, attaches it tothe'bolt'G. c is a sheave in the crotch of the lever F, and which-rollson the upper" edge of the top rail, D, to lessen the friction.

When the gate is to be opened, the lever is thrown forward, as in thered lines,.,which draws the bolt from its socket, and, at the same time,lifts the front stile C, and the forward ends of the rails sufiicientlyto clear The stile G is hung to the supplementary post B. This post isgrooved and slotted for the reception of the screws or 'boltsn a, (seefig. 2,) said screws passihg through the slot 9 in the post B, andfirmly screwed into the post A, to serve as guides for the post 13 inits vertical movement, as shown, (fig. 2.) V

This movement is accomplished by means of the circular cam J, providedwith the crank-pin d, and attached to the post A by the screw m, orequivalent device; This cam, in revolving, operates against the pin itthe gate, as is clearly shown in the figure. I V In the front stile, O,is ahole, 5. When it is desired to keep the forward end o'f the gateraised, the lower portion of the gate isolifted until the said holecomes above the top rail, D, when a suitable pin is inserted, and thegate is held up,vas shown, (red lines, fig. 2.) i

I), in the post B, lifting the said post vertically, and through At t,fig. 2, is one of a series of holes in the post A, for the insertion ofcheck-pins, to keep the cam J in any required position, and consequentlythe gate at the proper height.

One important feature in this gate is its cheapncss and simplicity ofconstruction. Being made almost entirely of wood, any farmer canconstruct it for himself.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, isi 1. The arrangement ofthe forked lever Fand sheave c with the articulation of the said lever on the bar a, bymeans of which the front stile, O, is lifted simultaneously with thedrawing back of the bolt G, in the manner and for the purposessubstantially as described.

2. Hoisting the gate by means of the cam J and pine, through the mediumof the slotted supplementary post B, and guide-bolts or screws, n n, or'their equivalents, when used substantially in the manner and for thepurposes as set forth.

3. The articulated arrangement of the bars a a a a in the stiles Cend C,en the pins, 1 2 3 4 6 7 8 9, 'by means of which theforward end of thegate may be lifted, and kept up by a pin inserted in the hole 5, overthe upper bar D, in'the manner as specified.

Witness my 'hand, this 6th day of April, 1868.
